Cerrowire has a rich history dating back to the 1920s, when it was founded by Hyman Cohn as Circle Flexible Conduit Co., Inc., primarily manufacturing armored cable and flexible steel conduits. Over the decades, the company evolved significantly, transitioning to produce insulated wires and expanding its offerings of various copper wiring solutions. In 2009, it rebranded from Cerro Wire and Cable to Cerrowire, illustrating its commitment to innovation in the building wire industry. Cerrowire now operates multiple state-of-the-art manufacturing facilities across Alabama, Georgia, Indiana, and Utah.

Today, Cerrowire stands as a premier supplier of copper and aluminum wire products for residential, commercial, and industrial applications. Their product range includes MC cables, building wires, portable cords, and specialty wires—all designed with cutting-edge features like unique exterior coding for easy identification. The company emphasizes strong customer service and reliable delivery while continually improving productivity through innovations such as their ReelRover wire handling device and CerroPack for tangle-free installations. As a proud American manufacturer under the Berkshire Hathaway umbrella, Cerrowire is dedicated to quality and excellence in every aspect of its operations.
